I think that not only should the author and the source be acknowledged, but permission should also be obtained. It is then up to the author whether any payment is requested. I would hope that most people in the folk music community would not request payment, but I can also understand that professional musicians need some payment for their work, particularly if it is for commercial purposes.

Awhile ago my friend Don Firth encountered unauthorized publication of his writing. Although his name was given, the source was not, and permission was not obtained. I wrote a piece in the Victory Review about this, here. After Don severly chatised the person who did this, he graciously gave permission.

I find through googling that much of my writing appears on other sites on the internet. So far, most have acknowledged me as the author, but only in a few cases have I been asked to give permission. While acknowledgement is sufficient for me, asking permission shows a bit of respect and common courtesy, and I might add, class.
